下载带有Cherrypy的docxtpl生成的文件 [英] Download docxtpl generated file with cherrypy
问题描述
我正在使用docxtpl生成Word文档，并且想知道一旦使用cherrypy生成的用户如何下载该文件，请参见下面的代码.
I am using docxtpl to generate a word document, and wondering how a user can download this file once generated using cherrypy, please see my code below.
我唯一能想到的解决方案是将其保存到www文件夹并创建指向该位置的链接，但是我敢肯定，这可以简化.
the only solution i could come up with is to save it to the www folder and create a link to the location, but i am sure this can be simplified.
代码:
import os, os.path
import random
import string
import cherrypy
from docxtpl import DocxTemplate
import sys
from auth import AuthController, require, member_of, name_is
import socket
reload(sys)
sys.setdefaultencoding('utf8')
cherrypy.config.update({'server.socket_port': 8000})
cherrypy.server.socket_host = '0.0.0.0'
cherrypy.engine.restart()
class Root(object):
_cp_config = {
'tools.sessions.on': True,
'tools.auth.on': True }
@cherrypy.expose()
def default(self, **kwargs):
print kwargs
if kwargs.get('csa_no'):
# print kwargs.get('csa_no')
tpl=DocxTemplate('csa_tpl.docx')
sd = tpl.new_subdoc()
p = sd.add_paragraph('This 1st insert')
sd2 = tpl.new_subdoc()
p = sd2.add_paragraph('This 2nd insert')
context1 = {
'date': 'jkh',
'company_name' : 'Test Footer',
'cost' : '10,000',

'Ammended_Contract_Value': '$320,000',
'project_manager': kwargs['project_manager'],
'construction_manager': 'Dane Wilson',
'date': '30/04/2016',
}
tpl.render(context1)
file_name_with_path = '/var/www/html/csa_documents/' + kwargs['sp'] + '-'+ kwargs['WO'] + '_' + kwargs['site'] + '_-_' + 'CSA' + kwargs['csa_no'] +'.docx'
file_name = kwargs['sp'] + '-'+ kwargs['WO'] + '_' + kwargs['site'] + '_-_' + 'CSA' + kwargs['csa_no'] +'.docx'
print file_name
print file_name_with_path
tpl.save(file_name_with_path)

推荐答案
简短的答案是，基本上，您需要编写一些内存流(例如 BytesIO )，并预先设置一些HTTP标头并返回 file_generator .您的问题与一个月前提出的问题几乎相同，并且此处是我的回答.
The short answer is that basically you need to write some in-memory stream (e.g. BytesIO), pre-set some HTTP headers and return a file_generator.
Your question is almost the same as one asked a month ago and here is my answer to it.
我在python3中为您起了一个小片段:
I've drafted a little snippet for you in python3:
from io import BytesIO
import cherrypy
from cherrypy.lib import file_generator
from docxtpl import DocxTemplate
class GenerateDocx:
@cherrypy.expose
def build_docx(self, *args, **kwargs):
iostream = BytesIO()
tpl = DocxTemplate('csa_tpl.docx')
...
# build your tpl here
...
tpl.get_docx().save(iostream)
cherrypy.response.headers['Content-Type'] = (
# set the correct MIME type for docx
'application/vnd.openxmlformats-officedocument'
'.wordprocessingml.document'
)
cherrypy.response.headers['Content-Disposition'] = (
'attachment; filename={fname}.docx'.format(
fname='put your file name here'
)
)
iostream.seek(0)
return file_generator(iostream)
UPD:我刚刚检查了如果处理程序的返回值具有 read()方法支持
UPD: I've just checked that the response body gets automatically wrapped with file_generator if the return value of a handler has read() method support
